LOCOMOTIVE ASH-PAN.

SPECIFICATION forming part of Letters Patent No. 620,707, dated March '7, 1899.

Application filed November 1, 1898. Serial No. 695,156. (No model.)

To aZZ whom it may concern:

Be it known that I, TAYLOR W. HEINTZEL- MAN, of Sacramento, in the county of Sacramento and State of California, have invented a certain new and useful Improvement in Locomotive Ash-Pans, of which improvement the following is a specification.

The object of my invention is to provide an ash-pan especially adaptable to use on locomotives having more than two driving-axles, but equally applicable to other types, in which ashes may be securely retained during such periods as desired and from which the ashes may be readily and completely discharged whenever required without necessitating manual labor or involving liability to clogging of a discharge passage or passages.

To this end my invention, generally stated, consists in the combination of an ash-pan having a lower discharge-opening, a guide-frame surrounding the discharge opening, a discharge-slide fitted to traverse in the guideframe and controlling the discharge-opening, and a fiuid-pressure mechanism for moving the discharge-slide; also, in the combination of an ash-pan body formed in two or more hopper-sections each having a lower discharge-opening, guide-frames surrounding the discharge-openin gs, discharge-slides each fitted to traverse in one of the guide-frames and controlling the adjacent discharge-opening, links connecting the discharge-slides,and a fluid-pressure mechanism for coincidently moving the discharge-slides.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a vertical longitudinal central section through a locomotive ash-pan, illustrating an application of my invention; Fig. 2, a partial plan view of the same; Fig. 3, an end view; Fig. 4, a transverse section on an enlarged scale; Fig. 5, a plan view of a guide-frame detached; Fig. 6, a transverse section through the same Fig. 7, a plan view of a discharge-slide, and Fig. 8 alongitudinal section through the same.

The body of the ash-pan, which is formed of sheet metal of proper thickness, is open at its top, the form and dimensions of which are such that when the ash-pan is supported below the grate of a locomotive fire-box it Will afford entrance for ashes or other solid matter 'ings.

which may be dropped from any and all portions of the grate. The construction illustrated is one which is designed for and has been found in practice to be desirably adapted to use in locomotives having more than two driving-axles, for which application the body of the ash-pan is made, as shown, in the form of two or more connected hopper-sections 1 l 1, each of which is preferably stiffened by angleirons at its corners and is downwardly and inwardly tapered toward a central dischargeopening 2 at its lower end. A guide-frame 3, of cast metal, having lateral grooves or guideways 4 and upwardly-extending flanges 5, is secured by bolts or rivets passing through its flanges to the bottom of each of the hoppersections, said guide-frames extending around the discharge-openings 2 thereof and stifiening the ash-pan structure in these locations. The side members of the guide-frames in which the guideways 4 are formed are eX- tended beyond one end of the frames, as most clearly shown in Fig. 5, in order to provide guiding-surfaces for the discharge-slides to be presently described when the latter are moved, so as to uncover the discharge-open- The distance between the .opposite guideways of each frame exceeds the width of the dischargeopening about which it is located, so as to prevent clogging or interference from solid matter which passes out of the discharge-passage. 7

Each of the discharge-openings 2 is controlled so as to be entirely closed or fully or partially uncovered, as may be desired, by a discharge-slide 6, which isa cast-metal plate, ribbed so as to be both strong and light and provided with lateral flanges 7, fitting the guideways 4 of the guide-frames. The tops of the discharge-slides fit truly against and make a tight joint with the guide-frames be tween the guideways and the discharge-openings, so as to prevent the clogging of the joints between the guideways and slides by ashes or cinders. Vhere, as in the instance shown, two or more hopper-sections and their accessories are employed, the several discharge-slides are adapted to be moved coincidently in covering and uncovering the dis= charge-openings. To this end the dischargeslides 6 are connected one to another, preferably by pairs of links or bars 8, which are coupled by pins or bolts 9, held in position by keys or split rings to lugs 10 on the ends of the slides adjacent to their sides.

Longitudinal movement on the guideways l is imparted to the discharge-slides to cover and uncover the discharge-openings as from 7 12 of which is coupled by a pin 13 to lugs' formed on the discharge-slide 6 of the rear hopper-section of the ash-pan. The cylinder 11 is most conveniently supported upon the frame 14 of the engine, as by hangers 15 connected thereto, and may also be connected by a frame 16 to the ash-pan. Fluid under pressure, preferably compressed air, which is ordinarily obtainable, or steam is admitted to and exhausted from either end of the cylinder 11 to efiect the movement of the piston thereof and the connected discharge-slides in one or the other direction, as desired, through pipes 17 18, controlled by an ordinary fourway cock 19, located in any desired and conveniently accessible position. The body of the ash-pan is in this instance shown as provided with lateral supporting-plates 20, which project over the top rails of the engine-frame 14 and are secured thereto through liners 21, resting thereon. The ash-pan may, however, be supported in any other suitable and preferred manner. The front and rear hoppersections are provided with the usual draftdoors or dampers 22.

The spaces between the hopper-sections afford room for the passage of the driving-axles of the engine, and the construction shown and described is therefore adaptable to use in engines having two, three, four, or five pairs of driving-wheels. It will, however, be obvious to those familiar with locomotive work that Where the number or spacing of the driving-axles renders it admissible an ash-pan having only a single hopper-section and its accessories may be employed without departure from the leading and essential features and governing principle of my invention.

I claim as my invention and desire to secure by Letters Patent- 1. In a locomotive ash-pan the combination of a body having a lower discharge-opening, a guide-frame having upwardly-projecting flanges secured to the body at the sides of the discharge-opening, and lateral guideways located below said flanges and at a greater distance apart than the Width of the dischargeopening, and a discharge-slide fitted to traverse in the guideways and control the discharge-opening.

2. In a locomotive ash-pan, the combination of a body having a lower discharge-opening, a guide-frame having upwardly-projecting flanges secured to the body at the sides of the discharge-opening, and lateral guideways located below said flanges and at a greater distance apart than the width of the dischargeopening, anda discharge-slide fitted to traverse in the guideways and to make tight slid ing joints with the guide-frame between said guideways and the sides of the dischargeopening.

3. In a locomotive ash-pan the combination of a body having sheet-metal walls, a lower discharge-opening, a frame having upwardlyprojecting flanges secured to the sheet-metal walls at the sides of the discharge-opening, lateral guideways below and at a greater distance apart than the width of said dischargeopening and a discharge-slide fitted to travel in said guideways, and means for operating said slide, substantially as described. I

4. In a locomotive ash-pan the combination of a plurality of hoppers having lateral supporting-plates adapted to be connected to a locomotive-frame, each hopper having a lower discharge-opening, a frame having upwardlyprojecting flanges secured to the walls of said hoppers at the sides of the discharge-openings guideways below and at a greater distance apart than the walls of said dischargeopenings, discharge-slides fitted to travel in said guideways, one for each discharge-opening, means connecting said slides, and means for applying power to said slides in a right line parallel with said guideways, substantially as described.
